Cisco 200-125 Online Practice Questions and Exam Preparation

Cisco 200-125 Online Questions & Answers

• Question 201:

  Which protocol supports sharing the VLAN configuration between two or more switches?

  A. multicast
  B. STP
  C. VTP
  D. split-horizon
  C. VTP

  ---

  "VTP allows a network manager to configure a switch so that it will propagate VLAN configurations to other switches in the network" VTP minimizes misconfigurations and configuration inconsistencies that can cause problems, such as duplicate VLAN names or incorrect VLAN-type specifications. VTP helps you simplify management of the VLAN database across multiple switches. VTP is a Cisco-proprietary protocol and is available on most of the Cisco switches.

• Question 202:

  Which two are advantages of static routing when compared to dynamic routing?(choose two)

  A. Security increases because only the network administrator may change the routing tables.
  B. Configuration complexity decreases as network size increases.
  C. Routing updates are automatically sent to neighbors.
  D. Route summarization iscompued automatically by the router.
  E. Routing traffic load is reduced when used in stub network links
  F. An efficient algorithm is used to build routing tables,using automatic updates.
  G. Routing tables adapt automatically to topology changes.
  A. Security increases because only the network administrator may change the routing tables.
  E. Routing traffic load is reduced when used in stub network links

• Question 203:

  What are the Popular destinations for syslog messages to be saved? (Choose three)

  A. Flash
  B. The logging buffer .RAM
  C. The console terminal
  D. Other terminals
  E. Syslog server
  B. The logging buffer .RAM
  C. The console terminal
  E. Syslog server

  ---

  By default, switches send the output from system messages and debug privileged EXEC commands to a logging process. The logging process controls the distribution of logging messages to various destinations, such as the logging buffer (on RAM), terminal lines (console terminal), or a UNIX syslog server, depending on your configuration. The process also sends messages to the console.

  Note: Syslog messages can be written to a file in Flash memory although it is not a popular place to use. We can configure this feature with the command logging file flash:filename.

• Question 204:

  Drag and Drop the PPPoE message types from the left into the sequence in which PPPoE messages are sent on the right.

  Select and Place:

  

  

• Question 205:

  The command frame-relay map ip 10.121.16.8 102 broadcast was entered on the router. Which of the following statements is true concerning this command?

  A. This command should be executed from the global configuration mode.
  B. The IP address 10.121.16.8 is the local router port used to forward data.
  C. 102 is the remote DLCI that will receive the information.
  D. This command is required for all Frame Relay configurations.
  E. The broadcast option allows packets, such as RIP updates, to be forwarded across the PVC.
  E. The broadcast option allows packets, such as RIP updates, to be forwarded across the PVC.

  ---

  Broadcast is added to the configurations of the frame relay, so the PVC supports broadcast, allowing the routing protocol updates that use the broadcast update mechanism to be forwarded across itself.

• Question 206:

  For what two purposes does the Ethernet protocol use physical addresses? (Choose two.)

  A. to uniquely identify devices at Layer 2
  B. to allow communication with devices on a different network
  C. to differentiate a Layer 2 frame from a Layer 3 packet
  D. to establish a priority system to determine which device gets to transmit first
  E. to allow communication between different devices on the same network
  F. to allow detection of a remote device when its physical address is unknown
  A. to uniquely identify devices at Layer 2
  E. to allow communication between different devices on the same network

  ---

  Physical addresses or MAC addresses are used to identify devices at layer 2.

  MAC addresses are only used to communicate on the same network. To communicate on different network we have to use Layer 3 addresses (IP addresses) -> B is not correct.

  Layer 2 frame and Layer 3 packet can be recognized via headers. Layer 3 packet also contains physical address ->.

  On Ethernet, each frame has the same priority to transmit by default ->. All devices need a physical address to identify itself. If not, they cannot communicate ->.

• Question 207:

  A network administrator creates a layer 3 EtherChannel, bundling four interfaces into channel group 1. On what interface is the IP address configured?

  A. the port-channel 1 interface
  B. the highest number member interface
  C. all member interfaces
  D. the lowest number member interface
  A. the port-channel 1 interface

  ---

  To create an EtherChannel interface and assign its IP address and subnet mask, use the following steps beginning in global configuration mode:

  Command Purpose Step 1 Router(config)# interface port-channel channel-number Router(config-if)# Creates the EtherChannel interface. You can configure up to 16 FECs and 1 GEC on the Catalyst 2948G-L3 and up to 4 GECs on the Catalyst 4908G-L3. Step 2 Router(config-if)# ip address ip-address subnet-mask Assigns an IP address and subnet mask to the EtherChannel interface.

  Step 3 Router(config-if)# exit Router(config)# Exits this mode. Optionally, you can remain in interface configuration mode and enable other supported interface commands to meet

  The IP address is assigned to the port channel interface, not the underlying physical member interfaces.

• Question 208:

  What are three reasons that an organization with multiple branch offices and roaming users might implement a Cisco VPN solution instead of point-to-point WAN links? (Choose three.)

  A. reduced cost
  B. better throughput
  C. broadband incompatibility
  D. increased security
  E. scalability
  F. reduced latency
  A. reduced cost
  D. increased security
  E. scalability

  ---

  IPsec offer a number of advantages over point to point WAN links, particularly when multiple locations are involved. These include reduced cost, increased security since all traffic is encrypted, and increased scalability as s single WAN link can be used to connect to all locations in a VPN, where as a point to point link would need to be provisioned to each location.

• Question 209:

  Which three options are switchport config that can always avoid duplex mismatch error between the switches? (Choose Three.)

  A. set both side on auto-negotiation
  B. set both sides on half-duplex
  C. set one side auto and other side half-duplex
  D. set both side of connection to full-duplex
  E. set one side auto and other side on full-duplex
  F. set one side full-duplex and other side half-duplex
  A. set both side on auto-negotiation
  B. set both sides on half-duplex
  D. set both side of connection to full-duplex

• Question 210:

  A Cisco router is booting and has just completed the POST process. It is now ready to find and load an IOS image. What function does the router perform next?

  A. It checks the configuration register.
  B. It attempts to boot from a TFTP server.
  C. It loads the first image file in flash memory.
  D. It inspects the configuration file in NVRAM for boot instructions.
  A. It checks the configuration register.

  ---

  Default (normal) Boot Sequence Power on Router - Router does POST - Bootstrap starts IOS load - Check configuration register to see what mode the router should boot up in (usually 0x2102 to read startup- config in NVRAM / or 0x2142 to start in "setup-mode") - check the startup-config file in NVRAM for boot-system commands - load IOS from Flash.
